I had these kind of marks after breastfeeding for 2 years (bad enough to make my Dr wince and express sympathy that 'this had happened to me at such a young age' and tell me that nothing could fix it except surgery). I've tried pretty much every lotion and potion over 7 years aswell as all kinds of painful aggravation techniques - but found that it really is just a question of massaging oil into the marks twice a day. Some oils work better than others - I've used lots and this gradually changed the texture. It's going to take time. What I found has worked the best and fastest for me is using vitamin E capsules with Virgin Coconut oil. This was something I tried when I was especially strapped for cash and it worked the best funnily enough. I just pierce the capsules with a needle and rub into my wet skin straight out of the bath, let it absorb a bit and then rub a layer of Virgin Coconut oil (from the Health shop or some supermarkets - but don't bother with refined)in over the top. Exfoliate twice a week gently - no more than that is necessary or good for skin. I don't know why this works so well - but it does. The texture of my skin is firmer and my deep marks are smoothing out - this started to happen very quickly.
